Specification of Letters Patent.

Patented May 19, 1914:-

To all whom it may concern Be it known that I, STEPHEN C. LAFLIN, a citizen of the United States, residing at Southbridge, in the county of Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Spectacles and Eyeglasses, of which the following is a specification.

My invention relates to improvements in spectacles. and eyeglasses, and hasfor its object to provide an improved construction of nose clamp or guard particularly intended for use in connection with spectacles, but applicable also to eyeglasses.

My invention comprises a bearing on the bridge adjacent its end, a nose clamp or guard, an attaching arm extending from the guard to the bearing, means for pivoting the attaching arm on the bearing and means for limiting the movement of the arm on its pivot.

The principal object of my invention is to provide means whereby a large latitude of adjustment of the nose clamp or guard is permit-ted in adapting them to, the various requirements of the wearers nose.

Another object of my invention is to provide attaching means for the nose clamps or guards which are more or less resilient or yielding whereby they will easily and comfortably adaptthemselves to the nose.

Another important object of my inven-. tion is to provide attaching means for the nose clamps or guards whereby the outer edge of the guard is left free and may be adjusted or turned in to engage the flesh of the nose and prevent easy displacement therefrom.

With these and other objects in view, the invention consists in the novel construction and arrangement of parts hereinafter described, delineated in the drawings and specifically claimed, it being understood that changes properly falling within the scope of what is claimed may be made, without departing from the spirit of my invention.

Similar numerals of reference are employed to denote corresponding parts throughout the several figures of the drawings.

In the accompanying drawings: Figure I is a rear elevation of a pair of spectacles embodying my invention. Fig. II is a top or plan view of Fig. I. Fig. III is an enlarged detail view taken in the same plane as Fig. II, a portion of the bridge being cut away for clearness of illustration. Fig. IV is a sectional detail view taken on line IVIV Fig. III. p

Referring specifically to the drawings, a pair oflense's 1 are connected in the usual manner by a bridge 2 having the well known loop or saddle 3 adjacent its ends upon one fold of which bosses or lugs i are secured. These bosses act as bearings for the arm 5 which is folded over or looped around the other fold of the bridge as shown in Fig. III, and attached to the nose clamp or guardfi, preferably at or near its rear edge. This arm is made of such a thickness and size that it may be readily adjusted or bent by the use of pliers or other instruments. The arm 5 is pivotally connected to the boss 4 by a pivot screw 7 threaded into the boss, as shown in FigQIII. This pivotal connection of the arm to the boss on the bridge allows the guard 6 to rock and adjust itself to the nose in av vertical plane. The amount of the rocking motion of the guard 6 is fixed and limited by recessing the end 8 of the arm 5 around the bridge fold to which the boss 4 is secured, as shown in Figs. III and IV, the amount of motion or rocking being determined by the amount of clearance left between the edge of the recess in the end S of the arm 5 and the bridge section which it embraces.

The nose clamps or guards are adjusted to the nose as follows: The distance between the nose guards 6 to accommodate the width of the wearers nose is regulated and adjusted by bending the loop or fold of the arm 5 which connects the guard to the boss 4 on the bridge. Further adjustment in this direction is also provided by the folds 3 of the bridge 2. The front or free edge 9 of the guard 6 may be bent or turned in to grasp the nose, so as to raise a mound or fold of flesh before it to retard displacement by bending the arm 5 which is connected at or near the rear edge of the guard. In-

spect-ion of Fig. III will show that a slight twist of the arm 5 near its connection to the guard will throw the front edge 9 of the guard in or out as desired.

The nose guard 6 adjusts itself to the nose in the vertical plane by means of the movement about its pivot on the boss 4; said motion being limited by the forked end 8 of the arm 5 contacting with the bridge memher which it embraces. The arm 5 may also be formed so that the pressure on the nose will be more or less yielding and resilient, the arm 5 acting'in the nature of a spring arm or member. This condition in view of the other adjustments described above is not essential and need not be adopted unless so desired.

I am aware that previous to my invention nose guards have been used on the bridge of spectacles but experience has shown that the range of adjustment of such constructions have hitherto been more or less limited and it is, therefore,thepurpose of my invention to improve such connections and increase the field of their effectiveness and adaptability.

It will be seen that by connecting the guard by means of the adjustable arm 5 the distance between the guards can be varied, the guard may be bent in or out, toward or away from the face, the free edge of the guard 9 may be bent in to engage the nose and raise a mound or fold of flesh before it to retard displacement, and an even and yielding pressure may be obtained on the nose, advantages hitherto not obtained.

Various methods of arranging, placing and pivoting the pliable arm may be devised without departing from the spirit of my invention. 1, therefore, do not desire to be limited to the exact details shown.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In spectacles and eyeglasses the combination of a bridge, a bearing on the bridge, a nose guard, an arm curving around from the nose guard toward the adjacent lens, one end pivoting on the bearing on the bridge and the free end supporting the guard, and a stop to limit the pivotal movement of the arm.

2. In spectacles and eyeglasses the combination of a bridge having a bowed central portion adapted to fit the wearers nose, the ends of the bowed portion extending rearwardly to a turn then forwardly to the lenses, a bearing on the bowed portion of the bridge, a nose guard, a pliable loop pivoted on the bearing and extending around the turn of the bowed portion of the bridge to the guard, and a stop to limit the pivotal movement of the loop.

3. The combination with a saddle bridge, of offset lugs carried by the crest portion of said bridge, horizontal pivots having threaded engagement with said lugs, and guards having arms mounted on said pivots for vertical tilting movement.

4. The combination with a bridge, of offset horizontally disposed pivots carried thereby, and guard arms having horizontally disposed loops formed therein, said arms each bearing a guard on one end of its loop and having the opposite end of the loop mounted on the pivot, whereby the guard is supported for vertical tilting movement.

5. The combination with a bridge, of a pivot carried thereby and offset relative to the inner face of the bridge, and a vertically tilting automatically adjustable guard supported by the pivot and held thereby against lateral movement relative to the bridge.

6. The combination with a bridge, of a horizontally disposed pivot carried thereby, said pivot being exteriorly disposed relative to the inner face of the bridge, and a guard supported by the pivot for vertical tilting but held against lateral displacement relative to the inner face of the bridge.

7 The combination with a bridge, of lens attachments carried thereby, said bridge having portions extending rearwardly of the lens attachments, horizontally disposed piv ots carried by and laterally offset relative to the rearwardly extending portions of the bridge, and nose guards having arms mounted on the pivot for vertical tilting movement relative to the remainder of the mounting.

8. The combination with a bridge having rearwardly extending portions and reversely outer forwardly extending ends, of lens clips carried by said forwardly extending portions and adjustable relative to the remainder of the bridge by bending of the forwardly extending portions, horizontally disposed pivots carried by the rearwardly extending portions of the bridge and disposed behind the lens clips, and guards having arms mounted on said pivots.

In testimony whereof I afiix my signature in presence of two witnesses.
